FILLIri'Gl-REPLENISHING LOQM.

1'0 an runom it "may concern:

Be it known that I, Jonas Nonrnnor, a citizen of the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings rcpresen ting like arts.

The invention to be hereinafter described relates to filling replenishing looms and more particularly to that type wherein the fillin carrier in a shuttle is replaced by another filling carrier at desired times. in such looms, wherein the filling carrier in the shuttle is replaced by another filling carrier having a supply of filling thereon, it is desirable that the shuttle assume such control of the new'filling as to. insure proper deii very of the same during the picking operations in order to prevent breakage, as well iinderstood by those skilled in the art; and,

with this fact in View, the aims and objects of the present invention will best be made clear by the following description and accompanyingdrawings of one form of means for carrying the invention into practical effect, it being understood that said invention is notcircumscribed by the details of said means, the true scope thereof being defined by the claims.

In the drawings: Figure 1 is a plan view of a sufiicient portion of the loom structure to illustrate the invention and i ts relation to adjacent parts, the lay being shown in front position and the shuttle as having just been supplied with a filling carrier; Fig. 2 is a view similar to that of Fig. 1, showing the moved a short distance on its back stroke and just prior to the pick, some of the parts being broken away or omitted to clearly show those beyond; Fig. '3 is a like view showing the lay as having moved further back and the shuttle as being picked, some of the parts being omitted; lgig. at is a side view of the right hand end of Fig. 1, showing more particularly the relation of the shuttle, filling end, and parts of the present invention at about the time of filling change; and Fig. 5 is an end View, looking in the direction of the arrow, Fig. l.

l E for moving the shuttle through the shed, the .neans for presenting a filling carrier to transferring position, shown partly in full and dotted lines, Fig. l, and supported, as by the bracket 1, the transfer-er F, and its associated parts by which a filling carrier may be transferred to the shuttle, may be of any usual or desired character and construction, and being well understood by those skilled in the art, need no further description. It is likewise usual in this type.of loom to lead the filling ends from the several carriers, which are to be transferred to the shuttle, as occasion demands, to a point at the loom side, asfor instance to apomt 2, Figs; 1, 2 and 3, in prolongation of the axis 3 of the filling carrier feeder, said feeder in the presentillustration being of the well knowii rotary type. When such form of filling feeder is employed and the ends of the filling .;l are held at the point stated, it is usual to provide a wheel. or guide G, Fig. 1, preferably of a diameter sufficient to deflect the filling ends toward the top of the shuttle box, so that the shuttle S of the selfthreadiug type may assume control of the filling or become threaded as it leaves the shuttle box. In practice, however, it he quently happens that the shuttle fails to assume control of the filling on the first pick owing to various causes, among which may be mentioned that the filling tails to drop into proper threading position on the top of the shuttle before the shuttle moves either backward with the lay or on its pick, and as the lay moves back, the filling, between the carrier and end, becomes deflected partly cross-wise over the end of the shuttle. and the shuttle fails to thread. The effect is that on the next pick the filling is broken.

The present invention may be employed either with the character of filling replenishing mechanism shown, wherein a feeder and filling end holder form parts, or it may be employed with any general character of 100 means operative at desired times to effect replenishment of the filling in a shuttle, and

,with this understanding, one form or embodiment of the invention will now be do scribed. 105

Mounted on the lay B is a member 5, which, for identification, may hereinafter heternred the filling director. This filling director preferably comprises a plate segeured to the lay suitable means, as, for 1610 instance, the screw bolt and nut 65, 7, the end of the said plate being downturned, as shown, and having a broadened or extended bearing to assist in maintainin it in fixed or ad justed position. The filing end director is shown as secured to the front portion of the lay and is provided with apart extending over the top 01"? the shuttle box, (I, said part reaching toward but stopping short of the rear Wall of the shuttle box and preferably having a curved edge 9. The curved edge 9 preferably extends from a oint 10, somewhat to the rear of the long1tudinal axis of the shuttle S when said shuttle is in the shuttle box and positioned for replenishment, to a point near the outer or end portion of the shuttle box, shown, the construction being such that when the lay is in-its forward position and a filling carrier has been transferred to the shuttle, the filling end t Will extend from the carrier 11, Fig. 1, to the holding point 2, and around the uide G, somewhat in front of the part 10 o? the filling end director, and as the lay moves back prior tg the pick, for instance, as indicated in Fig. 2, the filling 4 between the carrier and point 2 will be engaged 'by and extend under the director, the curved edge 9 and general character of the director maintaining the filling in alinement with the axial center of the shuttle or thread passage 12 of the shuttle threading block. As the lay continues rearwardly and the shuttle starts on its first pick, as indicated by Fig. 3, the lead of the filling from the holding oint 2 to the filling carrier 11 in the shutte S will be controlled by the edge 9 of the director to maintain such axial alinement of the filling with the shuttle or thread passage and thereby insure that the shuttle will assume deliverable control of the filling on the first pick.

As indicated in Figs. 4: and 5, the part erof the filling betweei the carrier in the shuttle and the guide or Wheel G not only extends somewhat backward but also upward, and the upward extension of the plate 5 of the director is such that the point 10 will engage above the filling as the lay moves back prior to the picking movement of ti shuttle, and thereafter, as the shuttle is picked and the direction of the part 4: of the filling becomes more and more nearly perpendicular to the lay, the curve of the edge 9-will maintain the desired axial alinement of the shuttle or thread passage and filling.

It will be obvious to those skilled in the art that the action of the filling director serves to maintainaproper position. of the filling between the carrier in the shuttle and the point of attachment of the filling end, so that the threading action of the shuttle on or rior to the first picking movement is ren ered more certain and consequent breakage of filling is reduced. it will see,

substantially as also be obvious that the filling ends may be secured or held at other points than that indicated by the present embodiment of the invention, and that it held at a proper position with respect to the lay and shuttle box, the guide or wheel G Would be unnecessary.

W hen the replenishing mechanism has transferred a fresh supply of filling to the shuttle and the latter has assumed control of the filling or become threaded, there will still be an end of filling extending from the selvage of the cloth to the point 2 where it is made fast. It is desirable that this end be not permitted to get into the shuttle-box, otherwise it is liable to be taken into' the shed by the shuttle on one of its picks, thereby producing a bad place in the cloth. The present invention obviates Ms defective action by the downwardly deflecting portion oi the director extending in front of the shuttle box which, as the lay goes back, de-' llects the engaged filling ends outside and to the front of the shuttle-box. This deflecting portion of the director and its action will best be understood from Fig. 5, wherein indicates the downwardly directing portion extending to the iiront ot the shuttle-box,

, and the dotted lines X indicate the position the filling end assumes as the lay moves back, it being finally disposed and deflected to the front ot the shuttle-box where all danger of being eiwaged by the shuttle and carried into the shed is avoided.

Many clnnges in form, shape and disposition oi the filling director will occur to those skilled in the art, and instead of being made of a plate it might be otherwise produced, and the present invention is intended to be generic in these respects, it being the first to provide a filling director iinmovably mounted with relation to the lay and operating to n'iaintain axial alinement oi' the. filling and shuttle or threading passage as the lay moves back.
